Metal Shavings in Oil – Is It Dangerous?

Did you ever notice metal shavings in engine oil? Do you wonder how they got there? The engine could have serious problems with its lubrication system if it has metal shavings. These metal shavings are caused by friction between metal parts.

While a small amount is normal in engine oil, a lot of metal particles is not. This could be a sign that the engine’s life expectancy is decreasing due to metal parts breaking down in engine oil from lack of lubrication.

What is the Normal Oil Content?

Although there are always tiny metal particles in engine oil, you may see them with your naked eyes. This could indicate a serious problem with the engine.

You may find metal shavings in engine oil. This can be very alarming. When oil is driven for over 10,000 miles, it’s common to see metal debris.

Oily oil – Signs and symptoms of metal shavings

  1. Damaged engine parts cause you to need to pull the engine apart.
  2. The engine vibrates and shakes
  3. Tickling and engine cranking sounds
  4. Poor engine performance

What happens to metal when it comes in contact with oil?

The engine oil causes metal parts to rub against one another when it is not properly lubricated. Metal shavings can be removed from the engine by constant rubbing. These metal shavings can then be absorbed into the engine oil. It is important to first check the oil level using a dipstick. If the oil level is not checked, you should replace it with a dipstick. don’t see oil on the dipstick If you’ve never changed your oil, it could be a problem.

Metal shavings in oil: Causes

1. Increased oil consumption

Damaged piston rings, a blown header gasket or a worn-out valve PCV can all lead to oil entering the combustion chamber. This could cause oil in the combustion chamber’s to start burning. This can cause increased oil consumption as well as a decrease in lubrication for the engine’s metallic parts.

2. Old engine oil

Engine oil can get clogged over time with dirt and other debris. This can cause a dearth of lubrication for the engine’s metal components. This can cause metal shavings to form in the oil, as the metal parts rub together.

3. Oil passage obstruction

The oil filter keeps the oil clear of any external contaminants. The oil filter can become clogged from dirt and other debris. It is important to have your oil filter cleaned regularly. clogged oil filter This will allow the bypass valve to return oil to the engine parts. This will block the oil passage, preventing proper lubrication.

How do you check for metal shavings?

A magnet is the best way to determine which engine part has corroded and how to get into engine oil. It is difficult to see metal parts through naked eyes. The magnet will hold the small metal shavings, which makes it easier to see metal debris.

Types of Metal Shavings

1. Copper metal shaving

These are yellowish. They are yellowish. As they rotate, rod bearings help keep the crankshaft in place and the connecting rod in place. Engine knocking will occur if the rod bearing is damaged.

2. Shavings of iron/steel metal 

Cast iron and steel are the main components of most engine parts. Iron debris from the engine oil can also result from metal shavings. You should have your engine block checked by a mechanic.

3. Aluminium Metal shavings 

The magnet will likely contain silvery metal debris. This is an indication that the engine has an aluminum component. Aluminum is used in a portion of the engine block. In some cars, the rod-bearing alloys can also be made from aluminum.

How do you remove metal shavings from the oil?

It is important to find the source of metal shavings in engine components as this can cause irreparable damage.

  1. Drain any oil that remains. Clean the engine of any metal shavings.
  2. Make sure to add fresh oil to the engine.
  3. Verify that the oil filter has been cleaned and is in good order.
  4. A magnet can be used to remove metal shavings. Magnets are able to remove large chunks of metal, but they will not work for small pieces.
  5. Make sure that any engine parts are inspected by a mechanic.


Metal shavings in an engine can cause engine problems. This is because metal parts rub against each other due to lack of lubrication. As a result, the engine could sustain severe damage.

Make sure to add new oil and make sure the oil filter works properly. This will ensure that all parts of the engine are properly lubricated.
